The problem
THE STEERING ARM MAY DEVELOP CRACKS DUE TO INSUFFICIENT FATIGUE LIFE IN THE MACHINE RADIUS OF THE TAPER AT THE STEERING KNUCKLE END.
What owners should do
INSTALL STEERING ARMS THAT HAVE BEEN MAGNA-FLUX INSPECTED FOR CRACKS AND SHOT PEENED FOR IMPROVED FATIGUE LIFE. THIS WILL BE DONE WITHOUT CHARGE.
